Amazed that this is still being updated!

This was one of the first apps I got for my first iPhone years ago. And it's just been updated. It's a great little app for a bit of quick mental arithmetic practice.

Really good app

as ive read through the comments people have been saying that answers are usually wrong, so far i havent seen a question which has a wrong answer. And also ive noticed that people dont remember the BIDMAS rule to all calculations, thats why there getting it wrong. For instance i saw someone say that 8+3x6=66, but it doesnt, it equals 26 because you have to multiply before u add numbers. This is simple maths people! xD

Good app tho, i like the whole roman numerals calculations :D
